Antenna and cap

Abstract

An antenna and cap, in an example implementation, can include a system, comprising a computing device, a clearance region coupled to the computing device, and an antenna comprising a first antenna portion and a second antenna portion. The first antenna portion can be coupled to the computing device and to the clearance region, and the second antenna portion can be coupled to the clearance region. The system can include a first cap coupled to the second antenna portion via a first interconnection, and a second cap coupled to the second antenna portion via a second interconnection. The first cap and the second cap can be coupled to the computing device.

 a first interconnection coupled to the second antenna portion at a first end and coupled to a first cap at a second end; and 
 a third interconnection coupled to a port and to the second antenna portion at a first end and coupled to the first cap at a second end, wherein the port is coupled to the clearance region. 
 
     
     
       2. The antenna of  claim 1 , wherein at least a portion of the antenna comprises a printed circuit board. 
     
     
       3. The antenna of  claim 1 , wherein the first cap and the third interconnection comprise a conductive metal. 
     
     
       4. The antenna of  claim 1 , wherein a position of the third interconnection comprises a tuned position. 
     
     
       5. The antenna of  claim 1 , wherein the third interconnection is a grounding point. 
     
     
       6. An antenna comprising:
 a first antenna portion disposed along a first direction; 
 a second antenna portion disposed along a second direction, the second direction being substantially orthogonal to the first direction; 
 a first interconnection coupled to the second antenna portion at a first end and coupled to a first cap at a second end, the first interconnection disposed along a third direction substantially orthogonal to a plane formed by the first direction and the second direction; and 
 a third interconnection coupled to the second antenna portion at a first end and coupled to the first cap at a second end, the third interconnection disposed along the third direction and coupled to a clearance region wherein a signal source is disposed in the clearance region. 
 
     
     
       7. The antenna of  claim 6 , wherein the clearance region is devoid of a conductive material. 
     
     
       8. The antenna of  claim 6 , wherein the first interconnection and the third interconnection comprise a conductive metal. 
     
     
       9. The antenna of  claim 6 , wherein the third interconnection is a grounding point. 
     
     
       10. The antenna of  claim 6 , wherein a position of the third interconnection comprises a tuned position. 
     
     
       11. The antenna of  claim 6 , wherein the first cap is comprised, at least in part, of a conductive material. 
     
     
       12. A method comprising:
 providing a first antenna portion disposed in a computing device, wherein at least a portion of the first antenna portion is coupled to a clearance region devoid of a conductive material and coupled to the computing device, wherein a signal source is disposed in the clearance region; 
 providing a second antenna portion coupled to the first antenna portion; 
 providing a first interconnection coupled to the second antenna portion at a first end and coupled to a first conductive cap at a second end; 
 providing a third interconnection coupled to a port and to the second antenna portion at a first end and coupled to the first conductive cap at the second end; and 
 providing the port, wherein the port is coupled to the third interconnection and the clearance region. 
 
     
     
       13. The method of  claim 12  wherein a position of the third interconnection comprises a tuned position. 
     
     
       14. The method of  claim 12  wherein the third interconnection is a grounding point. 
     
     
       15. The method of  claim 12 , wherein the first cap and the third interconnection comprise a conductive metal.
